Utility-Scale Battery Storage. The 2021 ATB represents cost and performance for battery storage across a range of durations (2–10 hours). It represents lithium-ion batteries only at this time. There are a variety of other commercial and emerging energy storage technologies; as costs are well characterized, they will be added to the ATB.
By using the formula of capacity utilization rate, we can calculate –. Capacity Utilization Rate = (Actual output/Maximum possible output)*100. Capacity Utilization Rate = 60,000/80,000. Capacity Utilization Rate = 75 %. From the above, we can also find the slack of XYZ company during the last financial year of 2016.
